Abstract

Disclosed are a liquid heating element and a method for production thereof, and more particularly a solid ingredient A, a liquid ingredient B produced from the solid ingredient A, a liquid heating element produced from the liquid ingredient B and a method for producing the liquid heating element. The solid ingredient is produced by heating activated carbon, kaolin, copper sulfide and phosphoric acid (H 3 PO 4 ) to a temperature ranging from 1,000 to 1,200° C. The liquid ingredient H is produced by mixing the solid ingredient A with silicon powder and distilled water and heating the mixture. The liquid heating element is produced by mixing the liquid ingredient B with ethylene glycol, leaving the mixture and then filtering the mixture. Since the liquid heating element is very stable and generates heat with minimum power consumption, it can be applied to various heat management systems.

Claims

       2. The solid ingredient A according to  claim 1 , wherein said activated carbon is in an amount of 25 to 70 parts by weight and kaolin or diatomaceous earth, copper sulfide and phosphoric acid are added in amounts varying depending on the amount of activated carbon. 
     
     
       3. The solid ingredient A according to  claim 2 , wherein 3 to 20 parts by weight of kaolin or diatomaceous earth, 4 to 20 parts by weight of copper sulfide and 55 to 110 parts by weight of phosphoric acid are added based on 40 parts by weight of activated carbon and heated. 
     
     
       4. The solid ingredient A according to  claim 1 , wherein said activated carbon, kaolin or diatomaceous earth, copper sulfide and phosphoric acid are mixed together and left for a predetermined period of time before being heated. 
     
     
       5. The solid ingredient A according to  claim 1 , wherein said activated carbon, kaolin or diatomaceous earth, copper sulfide and phosphoric acid are heated in the substantial absence of oxygen. 
     
     
       6. A liquid ingredient B produced by mixing a solid ingredient A with silicon powder and water and heating the mixture. 
     
     
       7. The liquid ingredient B according to  claim 6 , wherein 5 to 35 parts by weight of silicon powder and 300 to 850 parts by weight of water are added based on 30 parts by weight of said solid ingredient A. 
     
     
       8. The liquid ingredient B according to  claim 6 , wherein said solid ingredient A, silicon powder and water are heated at a temperature ranging from 90 to 110° C. 
     
     
       9. A liquid heating element produced by mixing a liquid ingredient B with ethylene glycol, leaving the mixture for a predetermined period of time and filtering the mixture. 
     
     
       10. The liquid heating element according to  claim 9 , wherein 30 to 50 parts by weight of ethylene glycol is added based on 650 parts by weight of the liquid ingredient B. 
     
     
       11. The liquid heating element according to  claim 9 , wherein said mixture of the liquid ingredient B with ethylene glycol is left for 15 to 30 hours. 
     
     
       12. A method for producing a liquid heating element, which comprises the steps of:
 preparing a solid ingredient A by heating activated carbon, kaolin or diatomaceous earth, copper sulfide and phosphoric acid (H3PO4) to a temperature ranging from 1,000 to 1,200° C.; 
 preparing a liquid ingredient B by mixing the solid ingredient A with silicon powder and water and heating the mixture; 
 preparing a liquid heating element by mixing the liquid ingredient B with ethylene glycol in a predetermined ratio and leaving the mixture for a predetermined period of time; and
